METHOD OF APPLYING DRIVING BANDS TO SPINDLES.

Application filed February 13, 1922.

To all whom it may concern:

Be it known that I, HARRY G. BAKER, a citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of lVlassachusetts, have invented anew and useful Improvement in a Method of Applying Driving Bands to Spindles, of which the following, together with the accompanying drawings, a specification.

My invention relates to a method of applying driving bands to spindles, such as are employed on spinning frames and similar machines, in which it is desirable tohave all of the bands with the same degree of tightness in order to insure uniform operai n o the machi e- In Patent No. 377,937, issued Feb. 14-, 1888, there is shown and described a. tubular braided band that is adapted to be applied to a spindle by passing the tipped ends of the band through the body portions thereof at marks located at equal distance from the tips. The marks are separated by a distance equal to the length of the band when passed around the driving drum and a spindle, so that when thev marks are brought together by pulling through the tipped ends, the band will be ofthe proper length and the projectingend portions may be cut off.

Difl iculties have been encountered in applying bands, marked as described in the above patent, to the spindles of spinning frames, owing to the fact that when one tip has been passed through the body of the band at one of the marks, it is necessary to allow this mark to pass behind the line of spindles before it is possible to insert the other tip through the other mark. With the marks at equal distance from the tips, it is difiicult, if not actually impossible, to hold on to the first tip which has beenpassed through a mark whileinseiting the other tip through its mark, and it is obvious that when the person applying the band Once loses hold of. one of-the tips, it is practically impossibletorfecover it, owing to the small clearance. between adjacent spindles, which prevents. insertion of the fingers therebe: tween.

The object of the-present invention is to provide an extremely simple method of applying a band to aspindle. A further obect of my invention-is to embody the principle of my improved method to the application of adriving tape for more than one Serial No. 536,228.

Fig. 8 is a plan view similar to Fig. 7 showing the tape applied to the spindles for driving the same.

Like reference characters refer to like parts in the different figures.

Referring to Fig. 1, a plurality of spindles 1 are arranged side by side, each spindle be ing provided with a whirl 2, by means of which the spindle is adapted to be driven from arotatable drum. 3. Each whirl 2 is connected to the drum 3 by means of an end less band 4, preferably composed of tubular braided material, and preparatory to being applied to a spindle, each band is provided with marks 5 and 6 which are separated by a distance equal to the length that the finished bands are to be when extending around the drum 3 and one of the whirls 2.

The ends of each band 4 are provided with pointed tips 7 and 8 beyond the marks 5 and 6, the distance between the tip ,8 and the mark 6 being appreciably greater than the distance between the mark 5 and the. tip .7, for a purpose to be hereinafter de scribed. Vthen it is desired to apply .a'band to a spindle, one end of the band is first passed around the drum 3 by inserting it between two adjacent spindles by means of a hook, or other suitable means, and allowing the .end of the band to drop behind the drum. The operator, in the meanwhile, holds on to the other end of the band in front of the spindle and byagain inserting band.

the hook, draws the loose end forward between the spindles, so that the band is then held at its ends in both hands, in front of the spindle, with the middle portion passing around the drum.

The next step in my method of applying a band to a spindle consists in passing the long tip 8 through the body of the band at the mark 5 as illustrated in Fig 2. The tip 8 is then pulled through the body of the band until the mark 6 is brought in front of the line of spindles 1 where it is held by one hand of the user. This movement of the mark 6 causes the other mark 5 to be drawn back of the line of spindles 1, but the length of band between the tip 8 and the mark 6 permits the user to keep hold of the tip 8 while at the same time he seizes the tip '7 and passes it through the body of the band at the mark 5, all as clearly illustrated in Fig.

The tips 7 and 8 are then pulled in opposite directions to bring the marks 5 and 6 together, as illustrated in Fig. 1, after which the projecting ends are cut off where they emerge from the body of the band. The spindle 1 will then be connected to the drum 3 by an endless band passing around the whirl 2, which is of the exact length to give the proper tension for driving the whirl from the drum. There will be no tendency for the marks 5 and 6 to become separated from each other because the strain on the band will cause the inserted end portions to be firmly held by the gripping force of that part of the body of the band which surrounds the ends.

Referring now to Figs. '7 and 8, there is shown an arrangement of four spindles 9, provided with whirls 10 which are adapted to be driven in unison from a drum 11 extending between opposite pairs of spindles 9. It has been heretofore customary to drive each set of these spindles by means of a flat tape passing around all of the whirls and the drum, the ends of the tape being sewed or laced together in order to make an endless It necessarily involves the expenditure of considerable time in order to properly connect the ends of the tape so that it will be tight enough to properly transmit power from the drum to the spindles.

As previously set forth, my method also contemplates the application of a driving hand or tape to a set of spindles arranged as shown in Fig. 7 When a tubular braid ed band is employed, it is obvious that the method is substantially the same as that described with reference to Figs. 1 to 1 inclusive, but when it is desired to employ a flat tape for driving the spindles, the length of tape 12 is so woven as to provide portions 13 and 14 which are tubular in form as compared to the remaining portions of the tape, which are woven to provide a flat web, similar to ordinary belting. One wall of each tubular portion 13 and 1 1 is separated from the other wall thereof by transverse slits 15, 15 and 16, 16, the portions 13 and 14 being so spaced apart that the distance between the nearest slits 15 and 16 is substantially the same as the length of the tape which is to be applied to the several spindles 9. The end portions of the tape 12,

which extend beyond the tubular portions 13 and 141:, are provided with tips 17 and 18, the tip 17 being spaced from the slit 15 by a distance which is appreciably greater than the distance separating the tip 18 from the slit 16.

In order to apply the tape 12 to the spindles, it is passed around the whirls 10 and the drum 11 and the ends are brought outside of the spindles on one side of the drum 11. The tip 17 is then inserted into the tubular portion 1 1 through the slits 16 and is drawn through until the tubular portion 13 is positioned in front of the spindles with the tubular portion 14 behind the spindles, the operator retaining hold of the tip .17, as shown in Fig. 7. The tip 18 is then inserted into the tubular portion 13 through the slits 15, after which, both tips are pulled to draw the tubular portions 13 and 14 together, as indicated in Fig. 2. The projecting ends of the tape are then cut off where they emerge from the tubular portions 13 and .14, so that the spindles will then be connected together by an endless band which is of the exact length to give the proper tension for driving the spindles in unison from the drum 11. The tubular portions will be prevented from separating for the reason that any strain on the tape will cause the ends thereof to be held by the gripping force exerted by the tubular portion which surrounds the same.

From the foregoing it is apparent that by my invention I have provided an improved method of applying driving bands or tapes to one or more spindles of a spinning frame or similar machine, in which it is desirable that all of the driving bands or tapes shall have substantially the same tension. Furthermore, by thepractice of my method, it is possible to readily apply a driving band or tape to a spindle without loss of time on the part of the operator, due to difliculties in securing the ends of the band or tape together. All that it is necessary for the operator to do is to pass the long end through one mark or slit and then, while still retaining hold of the long end, pass the short end through the other mark or slit after which the marks or slits may be drawn together and the ends severed, thus providing an endless band or tape.

While I have shown my invention with reference to a particular arrangement of spindles, it is obvious that. it may be employed in connection with other arrangements, and I desire therefore that only such limitations be imposed thereon as may come Within the scope of the appended claims.

I claim,

1. The method of applying a driving band to a spindle which consists in first providing tips on the ends of said band, then placing marks on the band at unequal distances from said tips, then passing said band around a drum and bringing both marks in front of the spindle, then inserting first one tip and then the other into the body of the band at said marks, and finally in pulling the tips to bring said marks together, the said tips always remaining in front of the spindle.

2. The method of applying a driving band to a spindle Which consists in first providing tips on the ends of said band, then placing marks on the band at unequal distances from said tips, then passing said band around a drum and bringing both marks in front of the spindle, then inserting the tip farthest away from its mark into the body at the other mark while the first mark remains behind the spindle, then pulling the tip through to bring the first mark in front of the spindle, then inserting the other tip into the body at the first mark While holding on to the first tip, and finally in pulling the tips to bring the marks together.
